A door and opener installed around 2002 is now over twenty years old, and the parts that fail first are predictable: torsion springs rated for a 10,000-cycle life are past due, nylon rollers have gone brittle, and the original opener's drive gear or capacitor is a common point of failure. Because this area sits in a severe-heat climate band, garage temperatures swing hard, and that heat cycling is rough on spring steel, weatherstripping, and the plastic housings on older opener units - it accelerates wear beyond what the calendar alone would suggest. We see a lot of early-2000s steel doors with sound panels but tired hardware underneath, which is good news: the door itself often doesn't need replacing, just the springs, rollers, and cables that have quietly been degrading in the heat for two decades.
